Total price
High pressure and high flow at the same time are the design point of this version: 350 bar operating pressure at 400 l/min nominal flow in size 25. Spool symbol V1 controls 4 ports across 3 switching positions, the pilot stage is fed and drained externally.
Key benefits
- 350 bar at 400 l/min nominal flow, up to 1250 l/min maximum flow.
- Spool symbol V1 in size 25 with internal spool position feedback for repeatable positions.
- External pilot oil routing on both sides keeps control pressure independent of the main circuit.
- Integrated digital axis controller, ±10 V command value, 24 VDC supply.
- 19.64 kg on a subplate to ISO 4401-08-08-0-05, 12-pole connector (11 + PE).
- NBR seals for HL hydraulic fluid in continuous duty.
